Question 7

Please select all the correct answers.

Which of the following are accurate comparisons betweencall-by-value and const call-by-reference?

Both protect against changing the caller’s argument.

Both are very fast for all sizes of objects.

Call-by-value copies the argument whereas constcall-by-reference does not

Call by value uses more memory than const call-by-reference inmaking the copy.

In a vector, which of the following statements is true?

Indexing vector access is range checked.

The range of legal index values for a vector is 0 to the valueof v.size()-1

To add a value use the member function v.push_front( )

To manage size of reserve use v.reserve(newReserve)

To increase or decrease a vector’s size v.new_size(newSize);

The index may not be an enum.

Question 17

Please select all the correct answers.

I want to have a nonmember function to have access to theprivate members of a class. The class must declare that function asa:

friend

inline

static

None of the above

Question 18

Basic operation overloading is similar to taking a simplealgebraic statement with two operands like y + 8and converting to a function, like:

+ (y , 8)

++ (y, 8)

= (y +8)
